Adds a 1s client-side ticker that rewrites .run-duration text from a
data-started-at attribute, so the header timer on /runs/{id}
increments every second while the run is active. When an SSE swap
lands a fresh header the new server-rendered value seamlessly takes
over; when the run goes terminal the template drops the attribute
and the ticker silently skips the node, leaving the final elapsed in
place.
Other templ_*.go churn is cosmetic — regenerator versions differ
between CI and local and only the filename field in templ.Error
callsites changed.
